Somewhat related to Shipping luggage from Narita Airport to Haneda Airport and storing it there, but not quite.
We arrive Haneda at 4:45am. We depart Narita 6pm. We have 4x large suitcases (we're a family with 2 young kids). We are on a single JAL itinerary the whole way, but have been told they do not arrange luggage transfer between airports.
Ideal world: We hand our bags to a luggage company at Haneda around 6am. Later that day, we pick them up (around 3pm) at Narita, and check in for our next flight.
This way, we can explore Tokyo for the day instead of lugging our suitcases all over hither and yon.
Is this possible? I've found some info on TA-Q-BIN and 'Hands Free Travel', but none of them are 100% clear on whether same day is possible. Certain pages say there is a 2-day minimum advance requirement for airport-bound luggage. Other pages specifically hint at same-day delivery.
Any help would be much appreciated :)
Our alternative plan is to limobus ourselves all the way out to Narita, then store/check our luggage and immediately turn around & get back into the city, but that feels like a waste of precious time in a city!
